o-charts frustrations

[BlackSea]

Once more
I have LMDE 6 ( Linux Mint Debian Edition). It´s based on Debian Bookworm
Kernel:
Linux x390l 6.1.0-17-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.69-1 (2023-12-30) x86_64 GNU/Linux
OpenCPN 5.8.4 from Debian Backport
O-Charts 2.0.1.9 from master catalog
"lsusb" output

Bus 001 Device 003: ID 1547:1000 SG Intec Ltd & Co KG SG-Lock[U2]

"dmesg" output

Character device exists

$ ls -la /dev/hidraw*

crw------- 1 root root 241, 1 Jan 15 09:30 /dev/hidraw1

BTW: neither opencpn package nor plugin installs udev.rule for dongle.
I created manualy

$ cat /etc/udev/rules.d/97-sglock.rules 
ATTRS{idVendor}=="1547", ATTRS{idProduct}=="1000", MODE="666"

Now when I start OpenCPN,

09:31:30.456 MESSAGE o-charts_pi.cpp:619 o-charts_pi::Using LD_LIBRARY_PATH: /usr/lib/opencpn:/home/xxx/.local/lib/opencpn:/usr/lib/opencpn

09:31:30.482 MESSAGE fpr.cpp:101 0
09:31:30.482 MESSAGE o-charts_pi.cpp:653 No Dongle detected

What's going wrong?

Ok. Found and solved
the good old days when plugins were installed via system package management are unfortunately over. For the communication between oexserverd and dongle you need libusb0.1-4 library, which is not installed automatically.

Solution:

sudo apt install libusb-0.1-4
